> FairScheduler: totalMaxShare is not calculated correctly in computeSharesInternal for
some cases.
> If the sum of MAX share of all Schedulables is more than Integer.MAX_VALUE ,but each
individual MAX share is not equal to Integer.MAX_VALUE. then totalMaxShare will be a negative
value, which will cause all fairShare are wrongly calculated.
